Abstract
The organic sources could supply adequate N, P, S, Zn, and B and have good effects on plant growth and development, water holding capacity (WHC), soil fertility and enhance the biological characteristics of the soil (Cooke,1982). However, the sole application of organic fertilizer is constrained by access to sufficient organic inputs, low nutrient content, and high labor demand for preparation and transport. Thus, the integration of organic and inorganic nutrient sources can improve and sustain crop yields without degrading soil fertility status. A combination of mineral and organic fertilizers is necessary to sustain and improve crop production on nutrient-depleted soils.
